Description

  TECHNICAL FIELD The present invention relates to grass revegetation that has both grass prevention and planting for the purpose of controlling weeds on roads, slopes, etc. and for landscape greening with short grass plants.

  Weeds that grow on roads and slopes have a high plant height, have poor prospects, hinder traffic safety, and adversely affect the surrounding landscape. Therefore, in recent years, a surface protection layer selected from the inorganic particles of Patent Document 1 and synthetic resins containing inorganic particles, a modified asphalt layer, and a herbicidal sheet in which at least three layers of a base material layer are laminated, and these three layers have been modified. Weeds do not grow by weeding and fixing a weed-proof sheet with at least 5 layers of a porous asphalt layer and a back surface layer selected from synthetic resin, rubber, inorganic particles and synthetic resin containing inorganic particles. Attempts have been made to do so.

  Patent Document 2 discloses that a black non-woven fabric having water retention, a black poly sheet that does not allow roots and water to pass through, and a black non-woven fabric having water repellency and root resistance are stacked in order from the bottom to form a single herbicidal sheet by thermal bonding. A large number of through-holes are provided at regular intervals, a black raschel net sheet of 2 mm is placed on the lower surface, and a seed sheet with seeds and fertilizer attached below it, and heat is applied so that the sheets are integrated. Attempts have been made to control weeds and green with a weed-proofing sheet formed on one sheet by bonding.

  However, although weed control by the weed control sheet of Patent Document 1 does not grow weeds, only one bare weed control sheet spreads and the deterioration of the local landscape is becoming a problem. Moreover, patent document 2 which aimed at greening and weed control has a problem which a black sheet accumulates solar heat highly according to a season, and prevents the germination growth of a plant.

  In order to solve the above problems, the present invention improves not only the herbicidal sheet using a herbicidal sheet but also the herbicidal greening sheet of the previous invention that combines grass prevention and greening, suppresses high heat storage in the sheet, The seeds germinate and grow well, have an excellent herbicidal effect, and short grass plants of the desired plants that do not interfere with the local landscape and traffic visibility can grow for a long period of time and can be easily constructed. It is to provide a herbicidal greening sheet.

  Therefore, in order to suppress the high heat storage of the herbicidal greening sheet and form a herbicidal greening sheet that can allow the desired plants to flourish, the coated paper, roots and water coated on both sides of the kraft colored core base paper in order from the top Penetration of a non-penetrating poly sheet and non-woven fabric with water retention to form a single herbicidal sheet by thermal bonding, and planting holes with a diameter of several tens of millimeters at regular intervals on the surface of the herbicidal sheet. Use a weedproof sheet. A hemp sheet adhered with a slow-acting fertilizer that promotes long-term growth of the desired plant is overlaid on the upper surface of the herbicidal sheet with planting holes, and fertilizer and seeds are mixed on the lower surface of the herbicidal sheet with planting holes. A seed sheet is formed, and the three sheets are bonded to form a single grass-proofing sheet.

  The herbicidal greening sheet has a diameter of 15 mm and a standard herbicidal greening sheet with 1,521 planting holes per square meter, with 39 vertical and horizontal holes per square meter as standard. The ratio of each area is about 73% for the grass-proofing sheet per square meter and about 27% for the planting hole, and the plants grown from the planting hole do not need mowing. A grass-proofing sheet with seeds such as centipeat grastef and blair.

  Lay the grass-proofing sheet on the road or slope where the weeding work has been conventionally done without any gaps with the seed sheet surface as the bottom surface, and fix it using anchor pins with hooks on the head. Greening with a herbicidal greening sheet that can grow the desired plant of short grass type from the planting hole and suppress the growth of weeds, which is about 73% of the herbicidal sheet portion.

  Revegetation using grass-proofing sheets can suppress the growth of weeds at the installation site, while allowing the desired plants to grow and grow, such as roads and slopes where weed management has been necessary. It is a grass-proofing sheet that can reduce administrative costs and improve road vision and improve the local landscape.

  In addition, the herbicidal greening sheet has a coating paper coated with kraft core raw paper instead of a conventional black non-woven fabric on the top, and a hemp sheet formed on it, so that these two sheets are exposed to solar heat. Reflection and mitigation, thereby reducing heat storage in the sheet and improving germination and growth disorders.

  In addition, the grass-proofing sheet made of a material that does not corrode easily is lightweight and easy to construct, and also ensures durability and suppression of water evaporation by multiple sheets, ensuring a long water retention period. It is also a herbicidal greening sheet that allows the desired plant to grow for a long time only by natural rainfall.

It is explanatory drawing which shows a coating paper. It is explanatory drawing which forms a weedproof sheet. It is a perspective view which shows the weed prevention sheet | seat with a planting hole. It is explanatory drawing which forms a grass prevention greening sheet.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a coated paper that forms the upper part of the weedproof sheet.
This coated paper is a kraft-colored coated paper 1 that coats the upper part of the core base paper 1A with a polyfilm 1B and the lower part with polyethylene 1C, repels water and does not pass through the roots, and stores solar heat compared to the conventional black nonwoven fabric. It is a paper weedproof sheet formed on coated paper that is difficult to corrode.

  FIG. 2 is an explanatory diagram showing a configuration of a weedproof sheet that blocks sunlight without storing heat and has water retention. In order from the top, water and planting intrusion, coating paper 1 to reduce sunlight light and heat storage, black poly sheet 2 to block planting and light underneath, light shielding and water retention under it Three sheets of the polyester black non-woven fabric 3 are sequentially stacked to form one sheet of grassproof sheet 4 that does not allow light to pass through thermal bonding. The three sheets constituting the weedproof sheet 4 are all made of a material that is lightweight and hardly damaged or corroded, so that the shape is maintained over a long period of time and the herbicidal effect is exhibited over a long period of time. Is done.

  FIG. 3 shows a herbicidal sheet with a planting hole. The desired plant seeds extend from the bottom of the herbicidal sheet 4 onto a sheet of 15 mm diameter planting holes 5 in a column of 39 planting holes per meter square. It is set as the grass prevention sheet | seat 6 with a planting hole which formed 1,521 planting holes per 1 square meter using 39 planting holes as a standard. Depending on the number of planting holes, the area of the planting hole in the grass protection sheet per square meter is about 27%, and the grass prevention part is about 73%. This ratio was the optimum ratio for the desired plant (short grass species) to grow while controlling weeds by test construction.

  FIG. 4 shows sheets for forming the grass prevention greening sheet. First, a hemp sheet 7 with a planting hole and a herbicidal sheet 6 with a planting hole adhered to a herbicidal sheet 6 with a planting hole attached thereto with a slow-acting fertilizer that reduces heat storage and promotes long-term growth of the desired plant. Underneath, a seed sheet 8 in which a short plant seed of a desired plant, a chemical fertilizer, and a slow-acting fertilizer are attached to a water-soluble paper sheet is placed and heat-bonded so that the sheets are integrated, and one sheet of herbicide Let it be a greening sheet 9. Since the seed sheet 8 has a property of dissolving when it absorbs moisture, the seed sheet 8 is dissolved by moisture on the ground surface, moisture from the through-holes, etc., and the encapsulated seed comes into direct contact with the ground surface and absorbs moisture to germinate and grow.

  The standard width of the grass-proofing sheet is 1 meter, and construction is done by removing dust and weeds and correcting the unevenness so as not to create a gap between the grass-proofing sheet and the laying surface. Then, the herbicidal greening sheet 9 is brought into close contact and laid in order from the top. At that time, each grass protection greening sheet is laid on top of each other about 5 centimeters so that there is no gap between adjacent grass protection greening sheets. Secure the seat to the installation surface.

  The herbicidal greening sheet is a sheet that combines grass prevention and greening that suppresses the growth of weeds and proliferates the short grass plants of the desired grass type, is lightweight and easy to install, and difficult to break or corrode, It is possible to retain the structure for a long period of time, and it is highly likely to be used as a greening material for roads and slopes where weeding management is necessary, and as a restoration greening material for natural environments in landscape formation etc. It is.
